Give me leave to place here, also, my acknowledgments to your Excellency, personally, for the facilities you have been pleased always to give in the negotiation of the several matters I have had occasion to treat with you, during my residence at your court. They were ever such as to evince, that the friendly dispositions towards our republic which you manifested even from its birth, were still found consistent with that patriotism of which you have continued to give such constant and disinterested proofs. May this union of interests forever be the patriot's creed in both countries. Accept my sincere prayers that the King, with life and health, may be long blessed with so faithful and able a servant, and you with a Prince, the model of royal excellence; and permit me to retain to my latest hours, those sentiments of affectionate respect and attachment, with which I have the honor to be, your Excellency's most obedient, and most humble servant. TO WILLIAM CARMICHAEL. New York, April 11, 1790. Sir,--A vessel being about to sail from this port for Cadiz, I avail myself of it to inform you, that under the appointment of the President of the United States, I have entered on the duties of Secretary of State, comprehending the department of Foreign Affairs. Mr. Jay's letter of October the 2d, acknowledged the receipt of the last of yours which have come to hand. Since that date he wrote you on the 7th of December, enclosing a letter for Mr. Chiappe. The receipt of his letter of September the 9th, 1788, having never been acknowledged, the contents of which were important and an answer wished for, I send you herewith a duplicate, lest it should have miscarried. You will also receive herewith, a letter of credence for yourself, to be delivered to the Count de Florida Blanca, after putting thereon the proper address, with which I am unacquainted. A copy of it is enclosed for your information.
